Hi all,
I am a new Pixhawk user and need your support/advice for PWM IO extension.
The VTOL design requests 20 PWM channels (8 motors, 2 wings, 4 elevon, 4 flaps, 2 rudder) but Holybro Pixhawk 4 provides only 19. I am pleased receiving your design recommendation solving this issue.
Pixhawk 4 Interfaces:

8-16 PWM outputs (8 from IO, 8 from FMU)
3 dedicated PWM/Capture inputs on FMU
Thanks
